Sedum plant named ‘Cherry Tart’

ABSTRACT

A new cultivar of  Sedum  plant named ‘Cherry Tart’ characterized by its foliage that is red in color with the red coloration retained without fading in spring, summer and fall, its leaves that are thick, ovate in shape, and with only slightly serrated, its production of 30 to 40 crowns the first year after vernalization, its numerous large inflorescences with flowers that are dark pink in color.

Botanical classification: Sedum hybrid.

Variety denomination: ‘Cherry Tart’.

CROSS REFERENCE TO A RELATED APPLICATION

This application is co-pending with a U.S. Plant Patent Application filed for a plant derived from the same breeding program that is entitled Sedum Plant Named ‘Lime Zinger’ (U.S. Plant patent application Ser. No. 13/573,635).

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Sedum plant, botanically of hybrid origin and known as Sedum ‘Cherry Tart’ and will be referred to hereinafter by its cultivar name, ‘Cherry Tart’. The new cultivar of Sedum is a hardy herbaceous perennial grown for use as a landscape and container plant and for use as a groundcover.

‘Cherry Tart’ arose from an ongoing breeding program by the Inventor in Hudsonville, Mich. The objective was to obtain a new cultivar of Sedum with dark cherry red foliage there is retained throughout the growing season combined with a compact mounded habit without the tendency to flop open in the center of the plant.

The new cultivar arose from a controlled cross made in July of 2009 between unnamed plants from the Inventors breeding program as male and female parents. The Inventor selected ‘Cherry Tart’ as a single unique plant in September of 2010 from the resulting seedlings.

Asexual reproduction of the new cultivar was first accomplished by tip stem cuttings in July of 2010 in Hudsonville, Mich. Propagation has determined the characteristics to be stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the characteristics of the new cultivar. These attributes in combination distinguish ‘Cherry Tart’ as a unique cultivar of Sedum.

-   -   1. ‘Cherry Tart’ exhibits foliage that is deep red in color with         the red coloration retained without fading in spring, summer and         fall.     -   2. ‘Cherry Tart’ exhibits leaves that are thick, ovate in shape,         with only slightly serrated margins (unique for a groundcover         type Sedum).     -   3. ‘Cherry Tart’ exhibits 30 to 40 crowns the first year after         vernalization (unique for a groundcover type Sedum).     -   4. ‘Cherry Tart’ exhibits numerous large (10 cm in diameter)         inflorescences with flowers that are dark pink in color.

The female parent differs from ‘Cherry Tart’ in being much shorter in height (70% shorter), and in having much smaller inflorescences, blue-gray foliage and much smaller leaves. The male parent differs from ‘Cherry Tart’ in being much taller in height and in having an upright plant habit, blue-gray foliage, and leaves that are larger in size. ‘Cherry Tart’ can be most closely compared to Sedum ‘Voodoo’ (not patented), Sedum ‘Fulda Glow’ (not patented), and ‘Lime Zinger’. ‘Voodoo’ is similar to ‘Cherry Tart’ in having a groundcover type plant habit and in having red foliage. ‘Voodoo’ differs from ‘Cherry Tart’ in having much smaller leaves that are more heavily serrated, smaller inflorescences that bloom earlier in the summer, thinner foliage and in showing more variability as it is a seed strain. ‘Fulda Glow’ is similar to ‘Cherry Tart’ in being a groundcover type plant and in having red colored leaves. ‘Fulda Glow’ differs from ‘Cherry Tart’ in having smaller leaves, foliage that turns green-red in the summer, smaller inflorescences that bloom 6 to 8 weeks earlier in the summer, thinner leaves and in showing more variability as it is grown as a seed strain. ‘Lime Zinger’ differs from ‘Cherry Tart’ most significantly in having lime green leaves with red picotee margins and in having more branched stems.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Sedum. The photographs were taken of a 14 month-old plant of ‘Cherry Tart’ and comparison plants as grown in a trial garden in Hudsonville, Mich.

The photograph in FIG. 1 illustrates the plant habit of ‘Cherry Tart’.

The photograph in FIG. 2 illustrates the inflorescences of ‘Cherry Tart’.

The photograph in FIG. 3 provides a comparison of the foliage of ‘Cherry Tart’ (left), ‘Voodoo’ (center), and ‘Fulda Glow’ (right). The colors in the photographs may differ slightly from the color values cited in the detailed botanical description, which accurately describe the colors of the new Sedum.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of the new cultivar as observed on 14 month-old plants of ‘Cherry Tart’ as grown in a garden in Hudsonville, Mich.
